Symmetry TFTs from String Theory. [PDF]
Commun Math Phys, 2023 We determine the $$d+1$$ d + 1 dimensional topological field theory, which encodes the higher-form symmetries and their ’t Hooft anomalies for d -dimensional QFTs obtained by compactifying M-theory on a non-compact space X .

Mechanisms for primordial black hole production in string theory [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We consider mechanisms for producing a significant population of primordial black holes (PBHs) within string inspired single field models of inflation. The production of PBHs requires a large amplification in the power spectrum of curvature perturbations

Superradiance in string theory [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance excludes some regions of Calabi-Yau moduli space. Regardless of the cosmological

Small cosmological constants in string theory [PDF]
Journal of High Energy Physics, 2021 We construct supersymmetric AdS4 vacua of type IIB string theory in compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit orientifolds and quantized fluxes for which the superpotential takes the form proposed by ...

A new gauge-invariant double copy for heavy-mass effective theory
Journal of High Energy Physics, 2021 We propose a new form of the colour-kinematics/double-copy duality for heavy-mass effective field theories, which we apply to construct compact expressions for tree amplitudes with heavy matter particles in Yang-Mills and in gravity to leading order in ...

T-duality in nonrelativistic open string theory [PDF]
Journal of High Energy Physics, 2020 Nonrelativistic open string theory is defined by a worldsheet theory that produces a Galilean invariant string spectrum and is described at low energies by a nonrelativistic Yang-Mills theory [1].

String theory and noncommutative geometry [PDF]
, 1999 We extend earlier ideas about the appearance of noncommutative geometry in string theory with a nonzero B-field. We identify a limit in which the entire string dynamics is described by a minimally coupled (supersymmetric) gauge theory on a noncommutative

The Weyl double copy from twistor space
Journal of High Energy Physics, 2021 The Weyl double copy is a procedure for relating exact solutions in biadjoint scalar, gauge and gravity theories, and relates fields in spacetime directly.

De Sitter vacua in string theory [PDF]
, 2003 We outline the construction of metastable de Sitter vacua of type IIB string theory. Our starting point is highly warped IIB compactifications with nontrivial NS and RR three-form fluxes.
